A stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an outdoor feeling while using the device.

A stride emulator device for efficiently utilizing human lea, power for transference to a rotary drive system including a pair of levers, at least two gears, at least two crankshafts having crank arms, and. where each lever includes a cam and cam track.

The invention relates to the field of sports and medicine, specifically to training devices, more particularly to an elliptical exercise device suitable for simultaneous training of shoulder and pelvic girdle muscles in a human. Accordingly, it is desirable to provide an exercise device for training trunk muscles, the shoulder girdle and the pelvic girdle in a human and, at the same time, to enable simulation of various motion patterns by activating different groups of muscles, joints, the locomotor system in a human in general and especially muscles which hold the vertebral spine. It is further desirable to enable optional correction of their load during the process of coordination of motor activity (locomotion) of the human body through simultaneous elliptical motions of hands and feet, which, in addition to the load on the shoulder girdle and the pelvic girdle muscles, simultaneously provide preferably stretching load on muscle groups which hold the vertebral spine.

An exercise machine which provides a continuously variable exercise path for a user, based on the use of a first crank which rotates about a primary axis, and a second crank which is user-rotated about a second axis on the first crank and which is linked to a stationary cog so that the first and second cranks counter-rotate.

Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.
